Great summary of types Brian! However I’ve noticed some minor bugs in the challenge. :slight_smile:

  1. Ub3r H4ck3r Challenge - Declare a variable of type Character called sadPlace. Set it to a happy emoji.
  2. var drama = happyPlace + sadPlace this line only works because these emojis are actually Strings and not Characters.

Yes, I agree with this, the solution to the challenge does not take account the setting of instructions to String / Double / Int / Character / etc. so kind of defeats the object of what the video is about. This could simply be addressed by improving the solution to the challenge.

I think there’s a problem. It asks to create 2 Characters vars, and then create a String var adding both Character vars, but it gets an error saying you can’t add 2 Character vars

Hi Brian, in the solutions the types are never declared but in the challenges is tells us to declare them. I’m a little confused here or am I not understand the challenge correctly? Thanks,Tim

Agreed - looks like these forums are not being monitored. Just starting with these videos and its disappointing to see the “solution” file does not provide he actual solution.

Hey Everyone … thanks for the feedback. I’ve gone ahead an updated both the challenge playground and challenge solution to fix the issues. Cheers!
